From the project
Open-source USB-C cable analyzer for e-marker identity, active/passive detection, declared capabilities, and full-pin continuity mapping.
usb-c-cable-analyzer.kicadsch is the native KiCad 10 Revision A review schematic. usb-c-cable-analyzer.kicadpcb is a four-layer placement-review board with the full 236-footprint circuit, four mounting holes, board outline, test access, safety markings, and exact schematic net assignments. It is deliberately unrouted and carries an explicit fabrication interlock. The generators keep the 50-node matrix mechanically consistent with ../pin-map.csv.

Usb c cable analyzer: common questions
What microcontroller does the Usb c cable analyzer use?
The Usb c cable analyzer is built around the SC1631, from the RP2040/RP2350 family.
How big is the Usb c cable analyzer PCB?
The Usb c cable analyzer measures 256 × 161 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Usb c cable analyzer?
236 components, from 101 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Usb c cable analyzer design files?
From the rwjblue/usb-c-cable-analyzer repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Usb c cable analyzer design in my own project?
The repository has no license, so all rights stay with rwjblue. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Usb c cable analyzer without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
